How newton rephson method is better than bisection method?
The Newton-Raphson method is generally more efficient than the bisection method because it has a quadratic convergence rate, meaning it can achieve much higher accuracy with fewer iterations, especially when the initial guess is close to the root. In contrast, the bisection method has a linear convergence rate and requires the function to change signs over an interval, which can lead to slower convergence. However, the Newton-Raphson method requires the calculation of the derivative and may not converge if the initial guess is far from the root or if the function is not well-behaved, making it less reliable in some cases. Overall, when applicable, Newton-Raphson tends to be faster and more efficient than the bisection method.
What is the advantages of secant method?
Advantages of secant method: 1. It converges at faster than a linear rate, so that it is more rapidly convergent than the bisection method. 2. It does not require use of the derivative of the function, something that is not available in a number of applications. 3. It requires only one function evaluation per iteration, as compared with Newton's method which requires two. Disadvantages of secant method: 1. It may not converge. 2. There is no guaranteed error bound for the computed iterates. 3. It is likely to have difficulty if f 0(α) = 0. This means the x-axis is tangent to the graph of y = f (x) at x = α. 4. Newton's method generalizes more easily to new methods for solving simultaneous systems of nonlinear equations.
Use the Bisection, Newton’s, and Secant Methods to find the solution of the equation x - cos x = 0 over the interval[0,pi/2] accurate to within error = 0.005, wherex is in radian. For Newton’s method, try initial guesses including x0 = 1?
Bisection Method: Begin with the interval [0, pi/2]. The midpoint of the interval is x1 = pi/4. Calculate the value of the function at x1: f(x1) = pi/4 - cos(pi/4). Since f(x1) > 0, the solution must be in the interval [0, pi/4]. Now consider the midpoint of this interval, x2 = pi/8. Calculate the value of the function at x2: f(x2) = pi/8 - cos(pi/8). Since f(x2) < 0, the solution must be in the interval [pi/8, pi/4]. Now consider the midpoint of this interval, x3 = 3pi/16. Calculate the value of the function at x3: f(x3) = 3pi/16 - cos(3pi/16). Since f(x3) > 0, the solution must be in the interval [pi/8, 3pi/16]. Continue this process, calculating the midpoint of the interval and the value of the function at the midpoint, until the difference between the lower and upper bounds of the interval is less than or equal to the error of 0.005. Newton’s Method: Try an initial guess of x0 = 1. Calculate the value of the function at x0: f(x0) = 1 - cos(1). Calculate the derivative of the function at x0: f'(x0) = 1 + sin(1). Calculate the next x-value using the Newton’s method formula: x1 = x0 - f(x0)/f'(x0) = 1 - (1 - cos(1))/(1 + sin(1)) = 0.6247. Calculate the value of the function at x1: f(x1) = 0.6247 - cos(0.6247). Calculate the derivative of the function at x1: f'(x1) = 1 + sin(0.6247). Calculate the next x-value using the Newton’s method formula: x2 = x1 - f(x1)/f'(x1) = 0.6247 - (0.6247 - cos(0.6247))/(1 + sin(0.6247)) = 0.739. Continue this process until the difference between two successive x-values is less than or equal to the error of 0.005. Secant Method: Start with two initial x-values, x0 = 0 and x1 = 1. Calculate the value of the function at x0 and x1: f(x0) = 0 - cos(0) = 0, f(x1) = 1 - cos(1). Calculate the next x-value using the Secant method formula: x2 = x1 - f(x1)(x1 - x0)/(f(x1) - f(x0)) = 1 - (1 - cos(1))(1 - 0)/(1 - cos(1) - 0) = 0.6247. Calculate the value of the function at x2: f(x2) = 0.6247 - cos(0.6247). Calculate the next x-value using the Secant method formula: x3 = x2 - f(x2)(x2 - x1)/(f(x2) - f(x1)) = 0.6247 - (0.6247 - cos(0.6247))(0.6247 - 1)/(0.6247 - cos(0.6247) - 1) = 0.7396. Continue this process until the difference between two successive x-values is less than or equal to the error of 0.005.

What is the defference between bisection method and newton method?
there are three variable are to find but in newton only one variable is taken at a time of a single iteration
What is advantages of bisection method?
In the absence of other information, it is the most efficient.
What is the advantages of using bisection method?
1. it is always convergent. 2. it is easy
What is the rate of convergence for the bisection method?
The rate of convergance for the bisection method is the same as it is for every other iteration method, please see the related question for more info. The actual specific 'rate' depends entirely on what your iteration equation is and will vary from problem to problem. As for the order of convergance for the bisection method, if I remember correctly it has linear convergence i.e. the convergence is of order 1. Anyway, please see the related question.
What is the Real root of 1-0.6x divided by x using bisection method?
The root of f(x)=(1-0.6x)/x is 1.6666... To see how the bisection method is used please see the related question below (link).
Disadvantages of the bisection method in numerical methods?
The main disadvantage of the bisection method for finding the root of an equation is that, compared to methods like the Newton-Raphson method and the Secant method, it requires a lot of work and a lot of iterations to get an answer with very small error, whilst a quarter of the same amount of work on the N-R method would give an answer with an error just as small.In other words compared to other methods, the bisection method takes a long time to get to a decent answer and this is it's biggest disadvantage.
What is the difference between interior optimum and boundary optimum?
The interior optimum method uses an a choice that is determined by the position of an agent at a tangency that rests between the curves of two points on a graph. The boundary optimum method analyzes the position of waves.
